i have to call 3-4 times a week to kathamandu and i have purchased calling cards from many websites. So far himtel is the best. Also, telenepal.com and zscomm.com are quite good ones. But, dont ever purchase from callingmadeeasy.com and amantel.com which are advertised in nepalnews.com. They tell 80 90 minutes with 4-5 star rating but you get to talk for 15 mins or less that too with lowest quality. If you know of any good sites or cards, pls share the info.
